Report Overwhelmed- 7 year old has developed tics in Tourette Syndrome and Tics Posted February 21, 2018 Hi Gaga, don't worry too much. My son has more tics when he was 7, 8 or 9. It began to diminish now when he gets older (teenager now). I found that when my son had beef when he was young, he had head jerking. When we stopped giving him the beef, his head jerking stopped, but it would take like 2 weeks to completely go away. He no longer has jerking now even he has little bit of beef. I found out the probiotic, multivitamin, sesame oil, sweet potato, dairy free diet, coconut water help him a lot. Hope these help. I understand it is hard for a mom to see her child experience all these.
